IMPROVEMENT m so ssms FOR SEWING-MACHINE SHUTTLE'S. a

Specification forming part of Letters Patent No. 91!,34, dated April 22, 1879; application filed December 10, ms.

concern: e Be it known that I, Dwren'r M. Omen, of Derby, in the county of New Haven and State of Connecticut, have invented a new and valuable Improvement in-Bobbins for Sewing- Machine' Shuttles; and I do hereby declare that the following is a full, clear, and exact dewription of the construction and operation of the same, reference being bad to the annexed drawing, making a part of this flcation, and to the letters and figures 0 reference marked thereon.

The flg'ure of the drawing is a representation, partly in section, of my bobbin, and the removable points to be used in connection therewith.

This invention has relation bobbins; and

- consists of two removahle'points, each consisting of a shank, how, and projecting point, in combination with a cylinder of paper havgfi flanges at each end, as will be hereinafter described, and particularly pointed out.

in e claim.

Referring to the drawing, A represents B made of paper or paper-pulp, in any le manner. Orepresents the woodon points, each being composed of the shanks o a: E per-cylinder, having outwardly-flaring D, the head 0, and the points proper, c. The

shanks D are placed within the cylinder A, and, while they abut against each other therein, the heads 0' firmly support the flanges, and'the points 0 projectoutward.

It will be observed that in the market it is only nry to purchase one 'set of points with several spools oi thread, as one set is readily a plied to each, and a great saving is thereby e ted. One set of points, it worn or damaged, may. he re laced by a new ones The heads 0' serve e ciently to prevent the thread from throwing over, and the shanks D serge to strengthen and support the paper tn What I claim as new, and desire to secure 'by Letters- Patent, is-

The removable lots 0, each consisting of the shank D, h O, and point e, in combination with the rcylinder A having flanges B, snbstanti as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
